Wow, this is the second time this "redirection to a filename with
spaces under Bash" issue pops up today, see the other one here:

  https://public-inbox.org/git/20190208031746.22683-2-tmz@pobox.com/T/#u

In short, Bash (when invoked as bash) doesn't conform to POSIX in this
respect; for a (too detailed) explanation see:

  https://public-inbox.org/git/20180926121107.GH27036@localhost/

Even our CodingGuidelines suggest the use of quotes around the
redirection's target.

issue, so I think you should ;)
